Age gap in couple

Yes.

Yes and Yes

I'm 15 years younger than my fiancée, and we are perfectly happy.

Yes... Why wouldn't they?

I just turned 43 one month ago, my person will be exactly 56 in 10 days. 🤷🏾 We're pretty obsessed with each other.

they can and they have

Sure
Why not

My last relationship, that lasted almost two years…. She was 15 years younger than me

i found many older women beautiful and intelligent. always hoped to find one available but never happened

At that age I think it can always work both ways.

No, not physically possible. Neil deGrasse Tyson said it is not.

Why not

There was a 21 year age gap between my husband and myself, we were very happily married for 18 years so the difference only showed in positive ways.

I was submissive to him and as he was leading me, I appreciated the wisdom his age bought him. I think in D/s relationships it's more common that the dominant partner is male.

The only thing I would say is that age can bring unforseen health issues. My husband died suddenly in 2024. If you are the younger partner, you will inevitably be left alone at some point so that is something you should be aware of. X

For me, once you reach adulthood, especially middle age, the difference between 41 and 56 becomes less meaningful. You are both older adults.

Does it matter?

I don't see what not. It is probably less likely than the opposite by raw statistics, but it doesn't really stretch the imagination. In general, I think the biggest challenge is just in how much cultural change happened in that fifteen year gap more than the specific genders at play.

Yeah some guys prefer younger some prefer older some prefer same age

It's just a matter of preference

Personally I favor the younger, but nothing against those who prefer the older
